Name: Tsuga heterophylla - Picea sitchensis - Abies amabilis / Rubus spectabilis / Polystichum munitum Forest Reference: NatureServe Biotics 2019 Description: This community is distributed within the Southern Very Wet Hypermaritime Coastal Western Hemlock Variant (CWHvh1), on the outer west coast of Vancouver Island from the Port Renfrew area northward, into the lowlands of northern Vancouver Island and the adjacent outer mainland coast northward to near Rivers Inlet. The elevational range of the CWHvh1 is 200 m in the south, to about 650 m above sea level in the north, but most sample sites for this association have been located between 10 and 100 m above sea level. These highly productive coniferous forests are situated on lower and toeslope seepage sites. <i>Tsuga heterophylla, Picea sitchensis</i>, and <i>Abies amabilis</i> are the dominant trees in the moderately open canopy (10-80% open). Regeneration of <i>Tsuga heterophylla</i> is prominent in the shrub and seedling layers. Other prominent species in the shrub layer include <i>Rubus spectabilis</i> and <i>Vaccinium parvifolium</i>. The herb layer features <i>Polystichum munitum, Blechnum spicant, Dryopteris expansa</i>, and lower coverage of rich-site indicators such as <i>Tiarella trifoliata, Athyrium filix-femina, Claytonia sibirica</i>, and <i>Galium triflorum</i>. Leading species in the well-developed moss layer are <i>Rhytidiadelphus loreus</i> and <i>Eurhynchium oreganum</i>. These sites are easily distinguished by their productive coniferous forest, abundance of <i>Rubus spectabilis</i>, and their location on lower and toeslope seepage sites.  Accession Code: urn:lsid:vegbank.org:commConcept:31736-{BECDAE23-98A2-44C5-AC1B-D8716568E5A8} Plot-observations of this Community Concept: 0
